Abstract

The authors fabricated an organic nanochannel field-effect transistor(FET) that is self-wired with highly conductive organic conductors. The advantages of the transistor are a short channel (approximately in length) and spontaneous formation of an active layer of the FET. Further, in principle, the carrier-injection barrier is absent at the interface of the organic metal and organic semiconductor. Thus, the transistor is highly conductive despite the narrow cross section of the channel. The FET characteristics of the nanochannel transistor exhibit the -channel enhancement mode behavior.
